Superior labral anterior-posterior (SLAP) tears: recent advances and outcomes

Abstract

Purpose of review The study presents a concise review of the published literature of disorders of the superior labrum, with a focus on reports published within the past 2 years. The aim of this review is to assist physicians with their assessment and treatment of lesions of the superior labrum. Recent findings The superior labrobicipital complex has many anatomical variations, some of which may be confused with superior labral anterior-posterior lesions. Various theories exist for potential mechanisms of injury to the superior labrum. Progress has been made into understanding the aspects involved in making a clinical diagnosis of a superior labral anterior-posterior lesion, with the physician's appreciation of the overall patient profile seemingly more important than any specific physical test. Imaging of the superior labrum continues to evolve. Research into the interobserver reliability of the arthroscopic diagnosis of a superior labral anterior-posterior lesion has demonstrated a poor level of agreement between clinicians. Surgical techniques for the treatment of superior labral anterior-posterior lesions and supraglenoid cysts continue to evolve. Summary Recent research has provided insights into understanding disorders of the labrobicipital complex. A clearer understanding of issues including normal age-related anatomy and function of the superior labrobicipital complex will aid in the diagnosis and treatment of superior labral anterior-posterior lesions.
